Description

Verfahren zur Herstellung haltbarer Emulsionen, Suspensionen und Kolloid-Dispersionen.Process for the production of durable emulsions, suspensions and colloid dispersions.

Es ist bekannt, daß sich Emulsionen und Suspensionen sowie Kolloid-Dispersionen flüssiger und fester Stoffe, wie beispielsweise solcher aus Petroleum, Tetrachlorkohlenstoff, Teerölen, Schwefel, Schwefelarsen, Metalloxyden und anderer mehr, herstellen lassen, indem man Seife als emulsionserzeugendes Mittel verwendet. It is known that emulsions and suspensions as well as colloid dispersions liquid and solid substances, such as those made of petroleum, carbon tetrachloride, Have tar oils, sulfur, sulfur arsenic, metal oxides and others produced, by using soap as an emulsifying agent.

Es ist ferner bekannt, daß mit Seifen aus sulfurierten Ölen (z. B. Rizinusöl-Sulfosäure) recht haltbare disperse Systeme entstehen sollen. It is also known that soaps made from sulfurized oils (e.g. Castor oil sulfonic acid) should result in very durable disperse systems.

Die obengenannten Emulgentien (Emulgierungsmittel) sind indessen nicht für alle technischen Zwecke brauchbar, da sie in vieler Beziehung dem angestrebten Zweck nicht entsprechen und in den meisten Fällen wegen ihres hohen Preises und der sich daraus ergebenden Unwirtschaftlichkeit ausschalten müssen. Meanwhile, the above-mentioned emulsifiers (emulsifiers) are not usable for all technical purposes, since they are aimed at in many respects Do not meet purpose and in most cases because of their high price and the resulting inefficiency must be eliminated.

Es wurde nun demgegenüber gefunden, daß man ausgezeichnet haltbare Dispersionen auf billigstem Wege und mit geringer Mühe erhält, wenn man Salze von hochchlorierten Fettsäuren, wie z. B. von Chlortranfettsäure, Chlorwollfett-Fettsäure, der chlorierten Harzsäure sowie anderer chlorierter hochmolekularer organischer Säuren, z. B. chlorierte Naphthensauren, verwendet. In contrast, it has now been found that they are extremely durable Dispersions are obtained in the cheapest way and with little effort if salts of highly chlorinated fatty acids, such as B. of chlorotran fatty acid, chlorinated wool fatty acid, the chlorinated resin acid as well as other chlorinated high molecular organic Acids, e.g. B. chlorinated naphthenic acids are used.

Die Darstellung der hochchlorierten Fettsäuren usw. erfolgt am besten nach dem im Patent 236 836 beschriebenen Verfahren. The representation of the highly chlorinated fatty acids etc. is best according to the method described in patent 236,836.

In gleicher Weise lassen sich die genannten Chlorprodukte in hervorragender Weise als Stabilisatoren in organischen Dispersionsmit, teln, wie Alkoholen, Aceton, Ölen, fetten Ölen sowohl wie Mineralölen u. dgl. verwenden. In the same way, the chlorine products mentioned can be used in an excellent manner As stabilizers in organic dispersants, such as alcohols, acetone, Use oils, fatty oils as well as mineral oils and the like.

Auch besitzen sie infolge ihrer amphoteren Löslichkeit die Eigenschaft, als Übertrager aus organischen in anorganische Lösungsmittel oder umgekehrt dienen zu können.Due to their amphoteric solubility, they also have the property serve as a transmitter from organic to inorganic solvents or vice versa to be able to.

Diese neuen emulsionsfördernden Mittel bieten gegenüber den bisherigen neben überlegenen technischen Eigenschaften vor allem den Vorzug der Wohlfeilheit, da zu ihrer Herstellung Abfallstoffe verwendet werden. These new emulsifying agents offer over previous ones in addition to superior technical properties, above all the advantage of cheapness, because waste materials are used in their manufacture.

Das Verfahren wird noch durch folgende Beispiele erläutert: I. Eine Lösung hochchlorierter Tranfettsäure in einer gleichen Menge Tetrachloräthan wird mit der zehnfachen Menge Wasser geschüttelt und der Lösung kohlensaures Kali zugesetzt. The method is illustrated by the following examples: I. A Solution of highly chlorinated fatty acid in an equal amount of tetrachloroethane is shaken with ten times the amount of water and added carbonate of potash to the solution.

2. Die nach Beispiel 1 hergestellte Lösung wird mit 20 Prozent Ventilatorschwefel versetzt, wobei der Schwefel in eine lange Zeit haltbare Suspension übergeht. 2. The solution prepared according to Example 1 is made with 20 percent fan sulfur added, whereby the sulfur passes into a long-lasting suspension.

3. Das Kaliumsalz der chlorierten Tranfettsäure wird mit dem Fünffachen seines Gewichts Wasser angerührt und dieser Lösung so viel Kupferoxyd zugefügt, daß ein dünnflüssiger Brei entsteht, welcher in der Kugelmühle oder in anderen geeigneten Mahlvorrichtungen so lange vermahlen wird, bis das Produkt kolloid-disperse Beschaffenheit angenommen hat. 3. The potassium salt of chlorinated trans-fatty acid is five times as high of its weight water and added so much copper oxide to this solution, that a thin-bodied pulp arises, which in the ball mill or in other suitable Grinding devices is ground until the product is colloid-disperse has accepted.

4. 1 Teil Chlorwollfettsäure wird in der gleichen Menge Alkohol gelöst mit 3 bis 4 Teilen Teeröl versetzt und mit Kalilauge neutralisiert. 4. 1 part of chlorinated wool is dissolved in the same amount of alcohol mixed with 3 to 4 parts of tar oil and neutralized with potassium hydroxide solution.

Man erhält so eine Kresolseifenlösung, die beim Eingießen in Wasser eine haltbare Emulsion ergibt. This gives a cresol soap solution which, when poured into water results in a long-lasting emulsion.

5. Io kg Kolloidgraphit werden mit 20 kg Wasser, dem 10 Prozent des Kaliumsalzes einer chlorierten Tranfettsäure zugefügt sind, in Kugelmühlen 60 Stunden lang vermahlen. 5. 10 kg of colloidal graphite are mixed with 20 kg of water, which is 10 percent of the Potassium salt of a chlorinated fatty acid are added, in ball mills for 60 hours grind long.

Hierauf wird das entstandene Produkt mit verdünnter Salzsäure I : 5 gefällt, das Koagulum durch Abnutschen und Pressen weitgehend vom Wasser befreit. Die entstandene Paste zerteilt sich ohne weiteres in Öl zu einer kolloidartigen Suspension, die über sehr lange Zeit hin haltbar ist.The resulting product is then treated with dilute hydrochloric acid I: 5 precipitated, the coagulum largely freed from water by suction and pressing. The resulting paste breaks up easily in oil to form a colloidal one Suspension that can be kept for a very long time.
